Title: A/d converter
Inventor: SAKURAI HIROSHI
IPC: H03M1/82
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To perform accurate digital demodulation by providing a presettable up-down counter and a PLL circuit for generating the sampling clocks of a demodulator acting at each cycle of PWM(pulse width modulation) input signals as signals for which an original PWM input frequency is multiplied by N. SOLUTION: This A/D converter is provided with a processing circuit for frequency dividing original PWM input signals to M and generating preloading signals to the up-down counter and output latch signals respectively from the rising and falling edges of the PWM input signals. The PWM input signals are inputted to the up-down counter, a preloading function is used and counting is started from an appropriate preset value. Thus, even in the case that the time of one cycle of the original PWM input signals itself fluctuates, the number of signals to be generated to the fluctuating one cycle of the PWM input signals is not changed. Thus, conversion more accurate than before is made possible.
